Will antibiotics mess up my supply?

I am pretty much 100% sure I have a UTI. I’ve had one before so this isn’t my first rodeo. The place I go to see a doctor for stuff like this was closed over the weekend so I’m barely gonna be able to go today & also hopefully be seen today. My only concern lies with the antibiotics... for 1 they always trigger a yeast infection & 2... will it ruin my milk supply? I have a pretty good supply going here & I’m working so hard to try & keep it up it would literally break my heart if it were to ruin it. So has anyone had to take antibiotics for any reason while breastfeeding & when you did what happened with your supply? 😭
